"Ha-ha. We're all Really Useful Engines, Thomas. We all have our own strengths."
— Sam, A New Friend on Sodor

Sam is a large American tender engine originating from the Virginian Railway.


Sam is a super-sized and super-strong locomotive. He came to the Island of Sodor to help Thomas and Percy with the construction of the Sodor Museum. He collected the heavy loads of rails and stone for the museum. He helped Percy and the bell for the museum back on the rails when Percy fell into a ditch. Afterwards, Sam pulled the bell up to the clock tower when Rocky could not. As a reward for his help, Sir Topham Hatt allowed Sam to lead the first group of people into the museum.

Sam and Logan later returned to the Mainland after their work on Sodor was done.


Hailing from the United States of America, Sam is the largest, strongest steam engine to ever visit the Island of Sodor. With a big heart to match his massive size, Sam is super-strong and will travel far and wide to help an engine in need.


Sam is based off of the Virginian Railway's Blue Ridge 2-6-6-6 class. He shares his number with a member of his class. The engine bearing this number was scrapped in 1960.


Sam is painted Persian green and black with white lining. He has his name painted near his cab, and "Virginian" painted on his tender in white.
